NEW YORK — Facebook’s latest multibillion-dollar acquisition — this time, it’s virtual-reality headset maker Oculus — is prompting some people to wonder whether CEO Mark Zuckerberg is living in an alternate reality.

Oculus, which launched on the crowdfunding site Kickstarter, doesn’t have a consumer product on the market. Its promise of virtual-reality goggles have generated buzz in the gaming community.

Zuckerberg, for his part, sees long-term implications in the technology — for communication, entertainment and beyond. He was right about mobile, and he has created the biggest online social network.

So, is he looney or visionary?

“Mobile is the platform of today, and now we’re starting to also get ready for the platforms of tomorrow. To me, by far the most exciting future platform is around vision or modifying what you see to create augmented and immersive experiences,” Zuckerberg said Tuesday.

Facebook’s investors seem to think Oculus’ promise is too far off. The company’s stock fell 7 percent on Wednesday to close at $60.38.

Beyond sticker shock, the WhatsApp and Oculus deals have raised questions about Facebook’s ability to innovate on its own. Some of the company’s most high-profile products, including the Facebook Messenger and Home services, have flopped.

A customer dining at Washington’s Oceanaire restaurant noticed an unusual line at the bottom of his receipt: “Due to the rising costs of doing business in this location, including costs associated with higher minimum wage rates, a 3% surcharge has been added to your total bill.”
